A controller for controlling a lighting system, the controller comprising: an interface arranged to communicate with one or more luminaires at a location to be illuminated; a memory arranged to store information, the information comprising a first illumination status of the location, and information of a first command causing the location to adopt the first illumination status; the interface further arranged to receive a second command comprising an instruction for the at least one luminaire to illuminate the location in accordance with a second illumination status which differs from the first illumination status; and a processor configured to determine whether to execute the second command based upon a comparison between a value associated with the first command and a value associated with the second command, the processor configured to calculate the value associated with the first command based upon a priority level value of the first command and a relevance factor associated with the first command, at a time of receiving the second command; and the processor configured to calculate the value associated with the second command based upon a priority level value of the second command.

Lighting system control

A method and apparatus for controlling distribution of illumination information in an illumination system, wherein illumination settings to be sent for storing at one or more luminaires are determined based on one or more priority metrics. Priority metrics may be based on previous usage of an illumination setting, or the content of an illumination setting for example. The determination and sending can be commenced by a trigger such as a time of day or a user input, and evaluation of priority metrics can be performed to so that illumination settings are stored intelligently based on a user profile, preference or schedule.

Illumination control

In a wireless mesh network, a battery operated node can select a parent node via which messages are routed to further nodes. The parent node can initially be selected based on signal strength. The node receives acknowledgements for messages sent, if they arrive. The node calculates a reliability indicator of the parent node based on the number of messages for which an acknowledgement has been received. If the reliability indicator exceeds a predetermined threshold the node selects a new parent node, based on second selection criteria. For example, the node with the next greatest signal strength.

Reliable reporting in wireless mesh network

For load balancing in a large-scale wireless mesh network, a device, a system and a method are provided for controlling data packet transmissions in the wireless mesh network, wherein a time slot is randomly selected within a determined answer interval for transmitting an answer responding to a received data packet.

Device and method for scheduling data packet transmission in wireless networks

In order to increase transmission reliability and transmission efficiency in the presence of interference at a transmitting or receiving node of a wireless network a device for controlling the node of the wireless network is provided, wherein the node is associated to at least one load unit. The device comprises a control unit that is adapted to adjust a communication mode of the node based on an operation state of the load unit.

Device and method for controlling a node of a wireless network

For improving the protection of a network against denial of service attacks and other hostile attacks, while keeping the operation of the network simple and efficient and considering restricted capacities of single network nodes, a control unit, a system and a method for operating a network with a plurality of nodes are provided, wherein at least one operation parameter of at least one node is adjusted based on a current network phase and a data packet received by the node () is processed based on the operation parameter.

Avoidance of hostile attacks in a network

For improving data packet transmission from a collector node to one or more network nodes without additional routing protocols or increase of the overall network load, a system and a method are provided, wherein a node and/or the collector node receiving an uplink data packet addressed to the collector node is adapted to store at least a sender node information and a transmitting node information as a reverse-route information for a predetermined time.
